When the drug ezetimibe was approved in 2002, it was hailed by its makers as a new tool for lowering cholesterol and fighting heart disease in patients. In clinical trials, the drug (marketed by Merck as Zetia) lowered levels of low-density lipoprotein or LDL, the so-called “bad cholesterol” associated with atherosclerosis, the thickening of blood vessels that can lead to stroke and heart attacks. Though LDL was also the target of the highly successful statin drugs, Zetia passed the FDA because it offered an alternative mechanism for reducing cholesterol levels, and soon was making billions of dollars a year for the pharmaceutical company. But as more and more people took the drug and more research was conducted, the scientific data did not match the marketing hype, with large clinical trials failing to find a protective effect against cardiac events and even finding in some cases that it made blood vessels thicker.
Sadly, the story of Zetia is not that unusual. In recent years, other drugs such as Vioxx and Redux have been come under fire when dangerous side effects or underwhelming clinical results became apparent after approval. These high-profile failures (and the inevitable ensuing lawsuits) have threatened to slow drug development, as pharmaceutical companies are understandably nervous about investing big money in a potential dud. Expensive new drugs that offer little to no improvement over pre-existing treatments also cause damage, by needlessly raising health care costs. So what changes can we make to the U.S. health care system to promote the creation of innovative new drugs worth their price tag?
Three authors, including G. Caleb Alexander of the University of Chicago Medical Center, proposed five not-so-easy fixes in a recent issue of Annals of Internal Medicine. Their strategy includes reforms of the FDA’s drug approval process, drug labels, and the payment strategy of insurance companies on the other. For drug companies that may not like the extra squeeze, incentives can be built into the system to sweeten the deal for developing more effective treatments and drugs for currently untreatable diseases. “Despite these challenges, the United States has a long history of successfully improving the safety and value of prescription drugs, and substantial progress can still be made,” the authors write.
